Hi, On bitcoinj 0.14 to use a bip32 custom path (eg bip44) we had to subclass DeterministicKeyChain and override getAccountPath(). Subclassing KeyChainFactory and KeyChainGroup was also required to make everything work.
Since bitcoinj 0.15 we could do KeyChainGroupStructure structure = new MyKeyChainGroupStructure(); KeyChainGroup.Builder kcg = KeyChainGroup.builder(params, structure); There is a new field in the Wallet protobuf format for the Key message: account_path. That field was not present in 0.14. So, when opening a 0.14 wallet from 0.15 code, the Wallet is not properly built because of account path is not persisted on the wallet file. What is the proper migration mechanism? Use a custom WalletProtobufSerializer? A custom KeyChainFactory? thanks! -- Oscar Guindzberg -- You received this message because you are subscribed to the Google Groups "bitcoinj" group.
